IMPROVEMENT IN SODA-WTER FOUNTAlNS.

Specification forming part of Letters Patent No. 166,440, dated August3, 1875; application filed January 29, 1875.

P To all whom 'it may concern:

Beit known that I, FREDERICK W. WIEsE- BROCK, of the city, county, andState of New York, have invented certain Improvements in Soda-TaterFountains, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, and theletters of reference marked thereon, making part of this specification,in which is represented a vertical sectional view of my improvement.

My present improvement is essentially a new article of manufacture, andis an improved fountain for soda-water and other gaseous liquids, or forconiinin g gas or any other like medium.

The nature of my invention consists in constructin g thefountain outofsheet-steel or sheetiron, and in then tinning the same, and after itsseveral parts are soldered together the vessel is then heated, and itsinterior surface is coated with paraine, and which provides anexceedingly neat, light, strong, and durable fountain, and in which alldanger of corrosion is, through the use of the parafline in connectionwith the tinning, securely guarded against.

The construction and operation of my invention are as follows: A isfthecylinder. B is the upper end piece or top, and C is the lower end pieceor bottom. These end pieces B C are each arched or dome-shaped, and areprovided each with a broad well-dened hoop, as shown at B1 O1 of theaccompanying draw ing. The top or end piece B is provided with anopening, b, at its center, and is as an article of manufacture the sameas Burnetts milk-can breast, patented November 21, 1871, No. 121,154,and the article now manufactured under which patent I contemplate usingas a top or end piece in the construction of my fountain, only makingthel same of sheet-steel or sheet-iron instead of a heavier material.The bottom or end piece C is in form the same as the top B, only it issolid and without any opening at its center, and is provided with a footrest or seat, O2. These severel features are constructed either ofsheet-steel or sheetiron tinned. The cylinder is then riveted, and' theend pieces B O, and the bung B2, and the foot or seat O2 are allsoldered together; or

the bung Bzmay be provided with a screwthread, and, after being passedthrough the opening b, may be secured by means of a nut, b', as clearlyshownin the drawing. rlhe fountain, being thus constructed, is nextheated, and its entire interior surface is coated with paraffine, whosewell-known qualities, in connection with the tinning, will preventcorrosion, or the `fibers of the lnaterial being eaten or otherwisedestroyed through the destructive action of any acid which the materialwhich the fountain may contain, or of vwhich it may be used as acarrier, possesses.

I am aware that years since an e'ort was made to introduce a cast-ironfountain, the interior surface 'of which was first enameled or linedwith porcelain or other similar vitreous matter, and then coated withmelted paraine; but, owing to its immense weight, the attempt proved tobe, comparatively speaking, a failure, and they have, owing to the greatdifficulty in handling them, in consequence of their weight, been almostentirely superseded by the sheet-metal fountain lined with blocktin.While fountains of this class-such, for instance, as the one embraced inmy patent of April 6,1875, No. 161,845-operate successfully, yet theyare expensive and laborious to manufacture, and, besides, areobjectionable on account of their weight. Now, a fountain constructedaccording to my presentimprovement is much lighter than a fountain linedwith sheet or block tin. It is far cheaper to manufacture thanl anyfountain now known to the trade that possesses the same degree ofstrength. As the thin film of parafne fills up all the pores which mayhave ben left open in the process of tinning it is impossible that theacids which the water contains should corrode the metal. Now, I am awarethat the process of coating metallic substances with parafne is not anew one; neither is the process of tinning sheet metal new. But neitherof these processes, singly applied, could be successfully employed inthe construction of a sheet-metal soda-water fountain. To attempt tocoat the. interior surface of either a sheet steel or iron fountain-notcast metal, but sheet-with a thin film of parafine, and-without anyother agent being employed, would be impl-noticable, because thepara'ine would soon peel o", leaving the uncoated surface of the Inet-alexposed to the destructive action of the acids. Now, it would be equallyas impracticable to attempt to use a sheet-metal fountain which issimply tinned, because as is well known to all who are practicallyfamiliar with the process of tinning either sheet iron or steel that itis impossible to so perform the process as not to leave certain of thepores of the metal uncovered or exposed. These exposed portions, comingin contact with the water or carbonio-acid gas, will soon become rustyand discolor the contents; but if the inside of the vessel is firsttinned and then coated with parafne when heated7 as in my presentinvention, so as to melt the paratliue'on the tinned surface, theparaftine will enter all the pores and crevices, and, coinpletely llingthe same7 render it impossible for the water or acid to rust the metal;and

as the coating of' parafne which I propose to use is designed to benot-hing` more than a merc filling,` up ot' the pores of the tinnedsurface, there is no danger of its peeling oft', in fact, the metal andparafne beco1ne as it were, so amalgamated that a very rough usage ofthe fountain will not wear ott' the saine.

Having now fully stated what I believe to be the condition ofthe art asapplicable to my present improvement, what I claim as new7 and desire tosecure by Letters Patent, is

A sheet-metal fountain tinned and coated with parattine, as a newarticle ot'manufacture.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
